<div class="textblock"><p>A plotting widget, displaying a polar coordinate system. </p>
<p>An unlimited number of plot items can be displayed on its canvas. Plot items might be curves (<a class="el" href="class_qwt_polar_curve.html" title="An item, that represents a series of points.">QwtPolarCurve</a>), markers (<a class="el" href="class_qwt_polar_marker.html" title="A class for drawing markers.">QwtPolarMarker</a>), the grid (<a class="el" href="class_qwt_polar_grid.html" title="An item which draws scales and grid lines on a polar plot.">QwtPolarGrid</a>), or anything else derived from <a class="el" href="class_qwt_polar_item.html" title="Base class for items on a polar plot.">QwtPolarItem</a>.</p>
<p>The coordinate system is defined by a radial and a azimuth scale. The scales at the axes can be explicitly set (<a class="el" href="class_qwt_scale_div.html" title="A class representing a scale division.">QwtScaleDiv</a>), or are calculated from the plot items, using algorithms (<a class="el" href="class_qwt_scale_engine.html" title="Base class for scale engines.">QwtScaleEngine</a>) which can be configured separately for each axis. Autoscaling is supported for the radial scale.</p>
<p>In opposite to <a class="el" href="class_qwt_plot.html" title="A 2-D plotting widget.">QwtPlot</a> the scales might be different from the view, that is displayed on the canvas. The view can be changed by zooming - f.e. by using <a class="el" href="class_qwt_polar_panner.html" title="QwtPolarPanner provides panning of a polar plot canvas.">QwtPolarPanner</a> or QwtPolarMaginfier. </p>
